In this study, insertion reaction of 10-undecen-1-ol (Un-OH) into the metallocene active center was investigated in the absence of olefin monomers. 10-Undecen-1-ol protected with trialkylaluminum (Un-O-AlR2; R = Me, Et, n-Bu, i-Bu) was treated with an En(Ind)2ZrCl2/MAO catalyst system. The react...

Propylene was copolymerized with 10-undecen-1-ol with the use of dimethylsilanylbis(2-methyl-4-phenyl-1-indenyl)zirconium dichloride as pre-catalyst metallocene and MAO or MAO and TIBA as cocatalyst. Comonomer incorporations from 0.1 to 0.9 mol% or 0.5–3.6 wt% were obtained. With MAO and TIBA a...

This paper describes catalytic applications of new orthopalladated complex/MAO systems in polymerization of ethylene and copolymerization of ethylene/10-undecen-1-ol. Orthopalladated complexes 1–5 were synthesized from tridentate ligands [C, N, S], with a general formula of PdLX, where L = [Ph2...

Thermal conductivity of pure methanol and three mixtures, methanol + n-propanol, methanol + n-octanol, and methanol + n-undecanol, has been measured with a cylindrical tricalorimeter technique (λ-calorimeter). Measurements were made at nine isobars, 0.1013, 1, 5, 10, 20, 30, 40, 50, and 60 MPa....

The challenging task of rhodium catalyzed hydroformylation with higher olefins is the efficient combination of the reaction and separation step for catalyst recovery and recycling. One promising concept is the use of organic solvent systems, which use a strong polar organic phase for the catalys...

This manuscript is the first report that discusses the phase behavior of a ternary system composed of water, nonionic surfactant C12E8, and 1-dodecene. The phase behavior (Kahlweit fish and tie lines at different temperatures) of this ternary system was investigated based on the phase behavior o...

A higher 1-olefin (1-dodecene) was oxidized to 2-dodecanone and other ketones in a modified Wacker system featured by omitting the use of copper chloride and employing tert-butylhydroperoxide (TBHP) as oxidant. Acetonitrile was the solvent of choice due to its higher selectivity towards 2-dodeca...

Hydroformylation of 1-dodecene catalyzed by water-soluble rhodium-phosphine complex, RhCl(CO)(TPPTS)2 (TPPTS: P(m-C6H4SO3Na)), in the presence of various mixed micelles was investigated. When either an anionic surfactant sodium dodecyl sulfate (SDS) or dodecylbenzonesulphonate (DBS), a nonionic ...

Linear alkylation (LAB) is an important intermediate in the detergent industry. This work deals with the suspension catalytic distillation (SCD) column used for synthesis of C12 alkylbenzene with benzene and 1-dodecene. A novel solid catalyst, which is friendly to environment, was selected. The ...

The hydroformylation of 1-dodecene was studied using Rh(acac)(CO)2 and a ligand as a catalyst in a thermomorphic multicomponent solvent (TMS) system consisting of N,N-dimethylformamide, decane and the olefin. High n-aldehyde/iso-aldehydes ratios were obtained with the bidentate phosphite ligand ...

Usually, phase equilibrium measurements are performed with pure substances. On the other hand, in technical applications, technical grade substances are used. In this work, the differences in the phase behaviors of these two grades were investigated. The phase behavior of technical grade, nonion...

The hydroformylation of 1-dodecene on a rhodium-biphephos catalyst complex exploiting a thermomorphic multicomponent solvent system was studied experimentally in a batch reactor in order to describe the kinetics of the main and the most relevant side reactions. The formation of the active cataly...

The palladium catalyzed methoxycarbonylation of long-chain olefin 1‐dodecene in a liquid/liquid biphasic system composed of methanol as polar phase and the substrate/product as nonpolar phase is reported. The immobilization of the palladium based catalyst in the methanol phase is affected by th...

We investigate the atomic behaviour of long-chain 1-dodecene adsorbed on Si(100) using a scanning tunnelling microscope with an exposure of 30 to 2.4 Langmuirs. Unlike previous reports on short-chain molecules, remarkable self-ordered assembly of molecules is not observed at room temperature, wh...

A method has been developed to improve the hydrogen production efficiency (HPE) by in-liquid plasma n-dodecane decomposition. A thin steam pipe is placed over the plasma electrode to recover the thermal energy emitted from the plasma to its surroundings. The steam generated by this energy is sup...

With the introduction of more strict emission legislations and advanced engine technologies, the contribution of engine oil to soot emissions from engines becomes more and more significant. In order to understand the sooting tendency of engine oil, experiments and chemical kinetic analysis were ...

There is an increasing industrial interest towards long-chain hydrocarbons, also due to the fact that they can be obtained from renewable organic materials. These substances are flammable and, under certain conditions, can explode. Nevertheless, very few experimental data are available on their ...

Vacuum distillation is selected as a technique for recycling in order to separate the mixture of a hydrometallurgical organophosphoric extractant from an organic diluent because of their low volatility and high selectivity. The experimental isobaric vapor-liquid equilibrium (VLE) data for the bi...

Quantitative vapour concentration measurements in evaporating sprays of n-dodecane and n-hexadecane at high pressure and temperature are presented in this paper. These two liquids have been selected as they represent realistic fuels such as diesel and biodiesel, and exhibit significantly differe...

The introduction of transition metal atoms into zeolites can significantly improve their catalytic performance. Herein, a series of Al free Fe-ZSM-23 zeolites were synthesized via hydrothermal synthesis. The samples were characterized by XRD, SEM, N2-physical adsorption, UV/Vis, FTIR, XPS, ICP, ...
